Tendinopathy is a prevalent musculoskeletal condition that affects both aging populations and individuals involved in repetitive, high-intensity activities, such as athletes. Current treatment options primarily address symptom management or involve surgery, which carries a significant risk of complications and re-injury. This highlights the need for regenerative medicine approaches that combine stem cells, biomaterials, and growth factors. However, achieving effective tenogenic differentiation remains challenging due to the absence of standardized differentiation protocols. Consequently, a review of existing research has been conducted to identify optimal biomaterial properties and growth factor protocols. Findings suggest that the ideal biomaterial for tenogenic differentiation should feature a 3D structure to preserve tenogenic expression, incorporate a combination of aligned micro- and nanofibers to promote differentiation, and require further investigation into optimal stiffness. Additionally, growth factor protocols should include an induction phase to initiate tenogenic lineage commitment, followed by a maintenance phase to support matrix production and maturation.
肌腱病是一种常见的肌肉骨骼疾病,影响老年人群体以及从事重复性高强度活动的个体,如运动员。目前的治疗选择主要是针对症状管理或涉及手术,而手术具有显著的并发症和再次受伤风险。这凸显了结合干细胞、生物材料和生长因子的再生医学方法的必要性。然而,由于缺乏标准化的分化方案,实现有效的腱分化仍然具有挑战性。因此,已对现有研究进行综述,以确定最佳的生物材料特性和生长因子方案。研究结果表明,用于腱分化的理想生物材料应具有三维结构以保留腱性表达,结合排列的微纤维和纳米纤维以促进分化,并且需要进一步研究最佳硬度。此外,生长因子方案应包括一个诱导阶段以启动腱性谱系定向,随后是一个维持阶段以支持基质产生和成熟。
